With these high performance kits we should look at hours used not miles done before we check them over,

How often do you rebuild your 2 stroke?
I'm kinda new to this sport, but I've pretty much fallen in love with riding. I think I've been out practicing on the bike at least 5 days a week the last two weeks since I got my bike running. As you can imagine the hours are clocking up on that rebuild pretty quickly. Eric Gorr says the 125 two strokes need new bottom ends every 80 hours. I think I'll go through 80 hours within the next year or two!
But I can deal with that, whatever.
But my service manual says i need to replace the piston every 7.5 hours. Do you guys really replace these things that often? I will stretch that out to a few months probably just because I'm learning to ride and I just don't have the guts to hold on and ride the pipe very often so it probably doesn't get beaten as much as some of the race bikes do, but still.
So I wonder... how often are you guys rebuilding your top ends I'm curious about the bottom ends too. I don't think I'll just split the case at 80 hours and replace the crank, but its kind of sobering to think the week I spent learning to rebuild the bottom end may only be good for a year or two.
my vapour has a run time, i would be on my 5th piston !!!
